GEOLOGY

Detailed explanation-1: -Livestock ranching. Agricultural expansion. Climate change. Lumber industry. Decrease in biodiversity. Decrease in climate services.

Detailed explanation-2: -Deforestation refers to the purposeful clearing or thinning of trees and forests. When deforestation occurs, much of the carbon stored by trees is released back into the atmosphere as carbon dioxide, which contributes to climate change.

Detailed explanation-3: -These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide (CO2).

Detailed explanation-4: -Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization.

Detailed explanation-5: -Generating power. Generating electricity and heat by burning fossil fuels causes a large chunk of global emissions. Manufacturing goods. Cutting down forests. Using transportation. Producing food. Powering buildings. Consuming too much.
